* Add support for CSS3 overflow-x and overflow-y properties.Michael Drake2014-06-012-4/+8
| | | | | | | | Now, overflow is a shorthand property setting both overflow-x and overflow-y. The getter for the computed overflow has been removed, and replaced with two for overflow-x and overflow-y.
* Various changes which modify API and ABI:Michael Drake2013-12-136-222/+65
| | | | | | | | | - Remove client allocation function. - Change node_classes callback not to yield array ownership to libcss. - Node bloom filters now built by, during selection libcss. - Added selection callbacks to get and set data on document nodes. Test suite, example, and documentation updated to match.
* Significantly optimise CSS selection performance.Michael Drake2013-12-012-0/+3
| | | | | | | | | | | | | | | | Now we pass a node bloom filter to css_get_style. That node bloom filter is filled with the node's ancestor element, class, and id names. Internally, libcss also generates a bloom filter for each selector chain. If the selector chain's bloom filter is not a subset of the node bloom filter, we know that the selector chain's rule does not apply to the node. This avoids the slow selector chain matching process. Other smaller optimisations to move the ruling out of selector chains for inapplicable media types and other reasons to before we start comparing rules from different sources to find the next rule. All this is now done in hash.c so select.c never sees the trivially ruled out rules.

The only computation that occurs is to convert EX units into EMs. This means that any EM units must be converted to PT by the client.
